Air pressure and atmospheric motion.
Explain the forces that generate winds Explain why there is well-developed westerly flow in the upper troposphere Differentiate between high and low pressure systems Compare and contrast surface and geostrophic winds Describe/read maps of constant pressure surfacesIdentify and discuss wind types and the forces that generate them Recognize surface and upper-level atmospheric maps and identify general patterns of windflow Explain monsoonal flow and land-sea breezes
Q: What makes the wind blow?
A: Air pressure differences.
1013 mb = 29.91 inches
Is the location for these pressure systems the northern or the southern hemisphere?
….., midlatitude cyclones, the ITCZ, thermal lows
Where are winds the fastest?
2. Surface winds
and lows associated
Monsoon in India
Weak monsoonal flow in southwestern US
from ocean to land
